Abstract (en)
[origin: EP1327838A2] An air conditioner with an ejector (40) includes first and second interior heat exchangers (31, 32) for performing heat-exchange between refrigerant and air to be blown into a compartment. The second interior heat exchanger (32) is disposed at a downstream air side of the first interior heat exchanger (31), and a decompression valve (33) for decompressing refrigerant in a dehumidifying - heating operation is disposed in a refrigerant passage connecting the first and second interior heat exchangers (31, 32). In a cooling operation, the first and second interior heat exchanger are used as evaporators. On the other hand, in the dehumidifying - heating operation, refrigerant decompressed in the decompression valve (33) is evaporated in the first interior heat exchanger (31) while bypassing a nozzle (41) of the ejector (40), and refrigerant is radiated in the second interior heat exchanger (32). <IMAGE>
